* In general, fine thread and needles are used
for sewing thin fabrics, and thicker threads
and needles are used for sewing heavy
fabrics. Always test thread and needle size on
a small piece of fabric which will be used for
actual sewing.
* Use the same thread for needle and bobbin.
* When sewing stretch, very fine fabrics and
synthetics, use a BLUE TIPPED needle. The
blue tipped needle effectively prevents
skipped stitches.
* When sewing very fine fabrics, sew over a
piece of paper to prevent yarn distortion.

To see if the needle is good, place the flat
side of the needle onto something flat (e.g
needle plate or glass).
The gap between the needle and the flat
surface should be consistent. Never use a
bent or blunt needle.
A damaged needle can cause permanent
snags or runs in knits, fine silks and silk-like
fabrics.
